This process involves neural circuits modulated by neuropeptides, such as corticotropin-releasing factor.150 Dopamine plays a central role in mediating the immediate reinforcing effects of drugs, and dysregulation of the dopaminergic system has been proposed as a predisposing factor for chronic substance use and the maintenance of addiction.151 Dopaminergic neurons originating in the VTA project to the NAcc, amygdala, hippocampus, and prefrontal cortex, while those from the substantia nigra project to the dorsal striatum.152 The activation or disinhibition of VTA dopaminergic neurons is critical for the potentiation of alcohol, nicotine, and opioids.152 Cocaine exerts its effects by inhibits dopamine reuptake by blocking dopamine transporters, thereby increasing or prolonging synaptic dopamine concentrations.152 Other central nervous system stimulants elevate synaptic dopamine via mechanisms such as dopamine reuptake inhibition, reversal of dopamine transporter function, and promotion of dopamine release.153 However, the mechanisms by which GLP-1 receptor stimulation modulates dopaminergic function remain unclear

Key Points The growth hormone receptor mediates a wide range of growth-related and metabolic actions, both directly and via insulin-like growth factor 1 (IGF-1) Receptor loss-of-function, predominantly owing to mutations in the extracellular domain, results in growth hormone insensitivity or Laron syndrome Receptor gain-of-function mutations are not known, but excessive receptor stimulation by growth hormone leads to gigantism, adult acromegaly and cancer (if autocrine growth hormone signaling is involved) The hormonereceptor complex is well-defined at a molecular level for the extracellular domain The growth hormone receptor exists as a constitutive dimer, and activation involves rearrangement of the receptor subunits to align the tyrosine-protein kinases JAK2 and Src bound below the cell membrane for activation JAK2 and the Src family of proto-oncogene tyrosine-protein kinases initiate signaling, the former involving the key transcription factor signal transducer and activator of transcription 5b This is a preview of subscription content, access via your institution Access options Subscribe to this journal Receive 12 print issues and online access $189.00 per year only $15.75 per issue Buy this article Purchase on SpringerLink Instant access to the full article PDF
